SSH tricks

As recently as a 2001, it was not uncommon to log in to a remote Unix system using telnet. Telnet is just above netcat in protocol sophistication, which means that passwords were sent in the clear. As wifi proliferated, telnet went from security nuissance to security disaster. As an undergrad, I remember running ethereal (now wireshark) in the school commons area, snagging about a dozen root passwords in an hour. SSH, which encrypts and authenticates connections, had been in development since 1995, but it seemed to become adopted nearly universally and almost overnight around 2002.

However, as Web pages become more like applications, the performance of scripts is having a bigger effect. With more and more applications being developed using Web technologies, improving the performance of scripts is becoming increasingly important. With a desktop application, a compiler is normally used to convert the source into the final binary. The compiler can take its time, and optimize as much as possible for good performance of the final application. Browsers are fairly good at achieving this, and Opera has one of the fastest scripting engines of any current browser.
